Preheat oven to 350°F (177°C). Line a baking sheet with parchment paper.
In a food processor, combine gluten-free flour, cheddar cheese, butter, salt, garlic powder, and onion powder. Pulse until crumbly.
Add cold water, 1 tablespoon at a time, pulsing until the dough comes together.
Transfer dough to a lightly floured surface and shape into a disk.
Roll dough out to about ⅛-inch thickness between two sheets of parchment paper.
Use a small fish-shaped cutter or small round cutter to cut crackers. Transfer crackers to the prepared baking sheet, spacing slightly apart.
Bake for 12–15 minutes, until lightly golden and crisp around the edges. Cool completely on the baking sheet to crisp further before serving.
